Sil-Kleer Filter Powder
Precoat Filter Aid

SIL-KLEER is a unique filter aid made from volcanic rock which is expanded and milled to specific grades by Silbrico's stringently controlled processing techniques. Purity is maintained by Silbrico's exclusive procedures for removing grit and other foreign substances. The resulting filter aid is an extremely pure, inert, white, light weight material having a unique interlocking structure with myriads of microscopic channels. It affords optimum flow rates and sparkling clarity in filtered substances. SIL-KLEER does not impart taste, odor or color to filtered liquids. Therefore, it is excellent for filtering food, beverage and pharmaceutical products.

Major Cost Advantage

Due to the light weight, 20 to 50% density advantage, SIL-KLEER offers twice as much filtration, pound for pound, than diatomaceous earth. A SIL-KLEER filter cake density is only 7 to 12 lbs. per cubic foot, or a dry density range of 6 to 10 lbs. per cubic foot. SIL-KLEER users can realize substantial savings in filtration operations with a better filter aid at less cost.

Non-Hazardous Waste

SIL-KLEER is not a hazardous waste and can be easily disposed of. Some cakes used for food processing can even be recycled as components in animal feed. In the U.S., this application has been approved by the Association of American Feed Control Officials (AAFCO).* *IFN 8-26-242

Safe - Less Than .1% Silica

Completely inert SIL-KLEER contains less than .1% silica (almost none) compared to D.E. with up to 60% silica! SIL-KLEER is also sterile and does not impart taste, odor or color to filtered products.

SIL-KLEER Fits All Standard Equipment

SIL-KLEER is excellent for use in both pressure and vacuum filtration equipment. When used with rotary vacuum filters, SIL-KLEER cakes exhibit less cracking than other filter aids. Simple testing beforehand will enable the selection of the optimum SIL-KLEERgrade and amount that is required.

Less Equipment Abrasion

Silbrico's exclusive processing system removes grit from the filter aid making SIL-KLEER as pure as possible. Less grit means less equipment abrasion and longer filter equipment life.

Easy Cake Release

Because of it's light weight, SIL-KLEER filter aids provide easy cake release at the end of a filtration cycle. This facilitates filter equipment cleaning. Manpower requirements are reduced and productivity is increased.

Full Grade Range

SIL-KLEER is produced in a wide range of grades to meet the flow rate and clarity requirements of almost every product and industry. Consult Silbrico for grade selections.

CODEX Approved

Inert-Codex Approved

Perlite filter aids are sterile and inert and are widely used for filtering liquids in the beverage, food and pharmaceutical industries. They do not impart taste, odor or color and are listed in the U.S. Food Chemicals Codex published by the National Academy of Sciences. This publication, which is a source of information on the quality and purity of food grade substances, is officially recognized by the U. S. Food and Drug Administration and has been adopted by many government agencies throughout the world.

Use of Spent Filter Cake as Animal Feed

A unique benefit to manufacturers using perlite filter aids in food processing is that spent filter cake is used as a component in animal feed in many countries throughout the world. This reduces spent filter cake disposal costs. In the U.S., this application has been approved by the Association of American Feed Control Officials (AAFCO).

Worldwide Availability

Perlite filter aids are available throughout the world. Any manufacturer desiring to use the product can usually obtain it packaged in bags or in bulk.

In the past 30 years, perlite filter aids have gained acceptance in almost every industry concerned with the separation of liquids and solids. The following list, although not all-inclusive, should give an indication of the many applications where perlite filter aids are being used.

Improved Backwashing

Because of the physical characteristics of SIL-KLEER, the cake is not mud-like and backwashes off the filter cloth or screen more completely. The SIL-KLEER cake flushes out of the filter without clogging pipes or drains.
